While I would like to keep the topic on Comfortis and suggest you post suggestions for other products under appropriate topic headings, I feel that I should begin by explaining why I am trying a new flea control product.
I used a topical product (Frontline Plus) for years and hated every minute of it. I hated putting the oily poison on top of my dog where it could spread onto everything in my home, including me. And the concern grew when I got a second dog that could ingest the poison. I suppose that if you had a dog with a thick coat of hair, you could part the hair and hide the poison on the skin deep down inside. But with a short-cut mini, it just runs all over the place.
But the straw that broke the camel's back was when we got fleas, though there are two possible reasons this happened:
- I was using the product only every third month during the winter months. A vet had told me that it lasted three months, even though the product specs say one month. I found the fleas at about 2-1/2 months.
- I wash my dogs once a week, which should be okay for a month. But it would seem it's not okay for 2-1/2 months.
I don't know of any forum members using Comfortis at this time, but I thought I'd post this just to share my thought process, thinking it through as I write. I do know we have many members who, like me, hate using the messy topicals.
I ordered Comfortis for a larger size dog so that I can split the tablets between my two dogs. Comfortis tells you not to do this, because the med may not be distributed evenly throughout the tablet. Doing so will certainly void any product warranties, so I'm not suggesting it for others.
However, I assume they say this for marketing purposes. They certainly don't put the meds into each tablet individually; they mix a batch just as you do when you are making cookies. Granted, you can get more chocolate chips in one cookie than another, however if they didn't mix the "batter" extremely well then they couldn't be sure that any one tablet had the right amount of meds.
I made the chart below to help me figure out a proper dosage for my dogs. As you can see, for most of the tablet sizes a dog at the high end of the weight range will get very close to the recommended dosage of 13.5 ml/lb. On the other hand, a dog at the low end of the weight range will get about double the recommended dosage. This tells me that a little more than the minimum recommended dosage shouldn't be harmful. Still, I want to use as close to the recommended dosage as I can guesstimate as I divide the tablet.
As you can see from the bottom of the chart, if I just split the tablet evenly Muka would get about 3.0 extra gm, and Pukalu about 6.5 extra. So after splitting the tablet, I'll take off a little less than a fifth from Muka's half and little less than a third from Pukalu's half.
Giving your dogs flea meds each month shouldn't need to be rocket science, but when I saw that a dog at the low end of the weight range would get twice the dosage as one at the high end, I thought it was worth taking a second look. I don't like putting poison in my dog in the first place, even if it is only supposed to kill the fleas.

: Vomiting is not common, but it is the most common side effect. So after giving them their first dose with dinner and a little water, I kept them at my side for an hour. If one had vomited, it would have been important to know which one. And to ensure that the other didn't eat the vomit. They seemed fine.Caution
: I received delivery of my Comfortis at the same time I received delivery of my annual supply of heartworm meds that I use May through October. The spec sheet for Comfortis warned of possible toxicity if you use a strong dose of the heartworm meds. I spoke to the pharmacist, and he said that a high dose would be using the dose for a dog at the low end of the weight range for the dose. So my chart made some sense after all!
Anyway, I don't like the idea of using both of these meds together so I'll speak to my vet about this before beginning with the heartworm meds in May.
